Mrs little create a box plot for the test scores on her latest math test. she finds that the interquartile range is 20 points. what is the Mean?
Mean ± 10 points = middle 50% (interquartile range).
More data needed.
To find the mean of the test scores, we need the values of the scores themselves, as the interquartile range alone does not provide enough information.
The mean is calculated by summing up all the values and dividing by the total number of values. So, if we have the actual scores, we can determine the mean.
